batch_request_api

Rails middleware gem to achieve Batch creates, updates and deletes.

• Customizable middleware
• Batch create, update and delete records sequentially or in parallel

Installation

Add this line to your application's Gemfile:

gem 'batch_request_api'

Or install it yourself as:

  $ gem install batch_request_api

Overview

After installing the gem, you get the middleware which will intercept requests to the following urls.

• batch_sequential (/api/v1/batch_sequential)
• batch_parallel (/api/v1/batch_parallel)

To use custom URLs, add a configuration block to your app initialization. Example:

BatchRequestApi.configure do |config|
  config.batch_sequential_paths = ['/api/v1/batch_sequential']
  config.batch_parallel_paths = ['/api/v1/batch_parallel']
end

API endpoint can be disabled by setting the path to a falsy value (nil/false).

Sequential Usage

This is the simplest way to implement batch. One network request to /api/v1/batch_sequential containing the batched payload will work with a regular rails controller.

Parallel Usage

This requires your controller to iterate and apply a transaction. One network request to /api/v1/batch_parallel containing the batched payload will need a code similar to this sample.

The batch request payload is available on the controller using params['json']

Batch Client

• Ember Addon (Ideal)
• Ruby Client

We expect that you will probably use the Ember Add on with this gem to make the batch request and receive a response.

If not, no worries we have built a sample Ruby Client for that reason.

Here are the sample payloads that the middleware expects for create/update/delete. The ruby client constructs the format for create action.

Batch Request Payload:

"requests": [
    {
      "method": "POST",
      "url": "/api/v1/movies",
      "body": { }, { }
    }
  ]
}

Batch Request Response:

[
  {"status"=>200, "headers"=>{}, "response"=>{}},
  {"status"=>200, "headers"=>{}, "response"=>{}}
]
